Description

Technical Field

[0001] This utility model relates to the field of rotary reducer technology, specifically a large-angle tracking rotary reducer. Background Technology

[0002] Rotary speed reducers are core transmission components widely used in heavy equipment such as engineering machinery, wind power equipment, port machinery, and mining equipment. They are primarily used to achieve high-torque, low-speed rotary motion control. Their technical fields encompass precision gear transmissions (such as planetary gears and cycloidal pinwheels), hydraulic motor integration, bearing support structures, sealing and lubrication systems, and intelligent control technologies. They are characterized by high load-bearing capacity, high transmission efficiency, high positioning accuracy, and long service life.

[0003] However, current rotary reducers require horizontal installation, but in mountainous projects with steep slopes, reducers with a fixed angle range may not be able to adapt to the terrain, making it impossible to adapt the tracking curve. Utility Model Content

[0004] The purpose of this invention is to provide a large-angle tracking rotary reducer to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes four adjusting components, each comprising a sleeve, with a telescopic column slidably connected inside the sleeve. The telescopic column has several locking slots, with each pair of locking slots corresponding to each other. The sleeve has two limiting slots, which correspond to the positions of the locking slots. Two threaded columns pass through the two limiting slots respectively. Each threaded column is connected to a driving component, which drives the two threaded columns to move synchronously along the axis of the threaded column.

[0006] Furthermore, the drive assembly includes a mounting housing, inside which two sleeves are fixedly connected. Two first helical gears are rotatably connected to each of the two sleeves, and the two first helical gears are threadedly connected to the two threaded columns.

[0007] Furthermore, the two threaded posts can each enter one of the two sleeves in a corresponding manner, and the two sleeves can each limit the movement of the two threaded posts in a corresponding manner.

[0008] Furthermore, the two first helical gears mesh with the two second helical gears in a one-to-one correspondence, the two second helical gears are connected to one end of two rotating shafts in a one-to-one correspondence, the two rotating shafts are rotatably connected to the mounting housing, and the other end of the two rotating shafts is provided with two third helical gears in a one-to-one correspondence.

[0009] Furthermore, the two third helical gears mesh with the two fourth helical gears respectively, and the two fourth helical gears are both sleeved on a transmission shaft. The transmission shaft is rotatably connected to the mounting shell, and one end of the transmission shaft extends through the mounting shell. A handle is provided on the end of the transmission shaft located outside the mounting shell. The mounting shell is fixedly mounted on the base plate.

[0010] Furthermore, a housing is fixedly mounted on the base plate, and a motor is fixedly mounted on the housing. A worm gear is provided at the output end of the motor, and the worm gear meshes with a gear component, which is rotatably connected inside the housing.

[0011] Compared with the prior art, the large-angle tracking rotary reducer provided by this utility model requires the base plate to be adjusted to a horizontal state when the rotary reducer needs to be installed. Due to the slope of the mountain, the drive shaft is rotated by turning the handle. The two threaded columns are directly slidably connected to the sleeve, which moves the two threaded columns so that they leave the two locking grooves respectively, allowing the telescopic column to move. The bottom of the telescopic column moves to contact the mountain. The length of the four telescopic columns extending from the sleeve allows the base plate to be adjusted to a horizontal state. Then, the handle is reversed to drive the threaded columns to slide in the opposite direction, so that the threaded columns re-enter the locking grooves, limiting the telescopic column and keeping the base plate in a horizontal state.

[0018] Please see Figure 1-5 The large-angle tracking rotary reducer provided in this embodiment of the utility model includes four adjustment components 6. Each adjustment component 6 includes a sleeve 61, and a telescopic column 62 is slidably connected inside the sleeve 61. The telescopic column 62 has several locking grooves 63, with each pair of locking grooves 63 corresponding to each other. The sleeve 61 has two limiting grooves 64, which can correspond to the positions of the locking grooves 63. Two threaded columns 65 pass through the two limiting grooves 64 one by one. Each of the two threaded columns 65 is connected to a drive component 7, which can drive the two threaded columns 65 to move synchronously along the axis of the threaded column 65.

[0019] When installing the rotary reducer, the base plate 5 needs to be adjusted to a horizontal position. Due to the slope of the mountain, the drive shaft 78 is rotated by turning the handle 79, which in turn rotates the two fourth helical gears 77, which in turn rotates the two third helical gears 76, causing the two rotating shafts 75 to rotate, which in turn rotates the two second helical gears 74, causing the two first helical gears 73 to rotate. The two threaded columns 65 are directly slidably connected to the housing 72, causing the two threaded columns 65 to move and exit from the two locking grooves 63, allowing the telescopic column 62 to move. The bottom of the telescopic column 62 moves to contact the mountain. The length of the four telescopic columns 62 extending from the sleeve 61 allows the base plate 5 to be adjusted to a horizontal position. Then, the handle is reversed to drive the threaded columns 65 to slide in the opposite direction, causing the threaded columns 65 to re-enter the locking grooves 63, thus limiting the telescopic column 62 and keeping the base plate 5 horizontal.

[0020] Preferably, the drive assembly 7 includes a mounting shell 71, inside which two sleeves 72 are fixedly connected. Two first helical gears 73 are rotatably connected to each of the two sleeves 72. The two first helical gears 73 are threadedly connected to the two threaded posts 65. Through the direct threaded connection between the first helical gears 73 and the threaded posts 65, the threaded posts 65 can be moved when the first helical gears 73 rotate.

[0021] Preferably, the two threaded posts 65 can be inserted into the two sleeves 72 one by one, and the two sleeves 72 can limit the two threaded posts 65 one by one. Through the sliding connection between the threaded posts 65 and the sleeves 72, the threaded posts 65 cannot rotate, and the threaded posts 65 can only move along the axial direction of the threaded posts 65.

[0022] Preferably, the two first helical gears 73 mesh with the two second helical gears 74 respectively, the two second helical gears 74 are connected to one end of the two rotating shafts 75 respectively, the two rotating shafts 75 are rotatably connected to the mounting housing 71, and the other end of the two rotating shafts 75 is provided with two third helical gears 76 respectively, so that when the two third helical gears 76 rotate, they can drive the two first helical gears 73 to rotate.

[0023] Preferably, the two third helical gears 76 mesh with the two fourth helical gears 77 respectively, and the two fourth helical gears 77 are both sleeved on a transmission shaft 78. The transmission shaft 78 is rotatably connected to the mounting housing 71. One end of the transmission shaft 78 extends through the mounting housing 71, and a handle 79 is provided on the end of the transmission shaft 78 located outside the mounting housing 71. The mounting housing 71 is fixedly mounted on the base plate 5. The rotation of the two handles 79 allows the two threaded pins 65 to enter or leave the locking groove 63 synchronously.

[0024] Preferably, a housing 4 is fixedly mounted on the base plate 5, and a motor 1 is fixedly mounted on the housing. A worm gear 2 is provided at the output end of the motor 1. The worm gear 2 meshes with a gear component 3, and the gear component 3 is rotatably connected inside the housing.

[0025] The working principle of this utility model is as follows: When installing the rotary reducer, the base plate 5 needs to be adjusted to a horizontal state. Due to the slope of the mountain, the drive shaft 78 is rotated by rotating the handle 79, which causes the two fourth helical gears 77 to rotate, which in turn causes the two third helical gears 76 to rotate, which in turn causes the two rotating shafts 75 to rotate, which in turn causes the two second helical gears 74 to rotate, which in turn causes the two first helical gears 73 to rotate. Through the direct sliding connection between the two threaded columns 65 and the housing 72, the two threaded columns 65 are moved, causing them to leave the two locking grooves 63 respectively, allowing the telescopic column 62 to move. The bottom of the telescopic column 62 moves to contact the mountain. By the length of the four telescopic columns 62 extending from the sleeve 61, the base plate 5 can be adjusted to a horizontal state. Then, the handle is reversed to drive the threaded columns 65 to slide in the opposite direction, causing the threaded columns 65 to re-enter the locking grooves 63, thus limiting the telescopic column 62 and keeping the base plate 5 in a horizontal state.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
